Description
FIELD
[0001] The subject matter herein generally relates to driving
safety.
BACKGROUND
[0002] Vehicle bodies generally have an A-shaped pillar between
each of the front doors and front windshield, used to protect the
driver. In order to strengthen the A-pillar, the width of the
A-pillar is wide. Therefore, car driving especially during turning
is dangerous; the A-pillar can block the driver's sight and form a
blind region. Generally to reduce the blind region concave or
convex mirrors can be fitted to the front windshield. However,
concave and convex mirrors give a distorted image to the
driver.
BRIEF DESCRIPTION OF THE DRAWINGS
[0003] Implementations of the present technology will now be
described, by way of example only, with reference to the attached
figures.
[0004] FIG. 1 is a diagrammatic view of a part of vehicle including
a blind region mirror structure, according to an embodiment of the
present disclosure.
[0005] FIG. 2 is a diagrammatic view of a blind region mirror
structure shown in FIG. 1.
DETAILED DESCRIPTION
[0006] This disclosure provides a blind region mirror structure for
a vehicle in which the driver can see the surrounding scene without
distortion.
[0007] A vehicle comprises a vehicle body, a front windshield, a
left front door, a right front door and at least one blind region
mirror structure. The vehicle body includes at least one A-pillar,
the blind region mirror structure being set on the A-pillar.
[0008] The blind region mirror structure comprises a first lens
module and a second lens module, the first lens module is located
outside of the vehicle and the second lens module is located inside
of the vehicle. The first lens module includes a first convex lens,
a first concave lens, a first reflection mirror, and a second
reflection mirror. The first convex lens is mounted away from the
A-pillar; the first reflection mirror is opposite to the first
convex lens and mounted on the A-pillar. The first concave lens is
set between the first convex lens and the first reflection mirror,
the second reflection mirror aligns with the first reflection
mirror and is mounted on the front windshield. The second lens
module includes a third reflection mirror, a fourth reflection
mirror, a second concave lens, and a second convex lens. The third
reflection mirror is aligned with the second reflection mirror and
is mounted on the front windshield; the fourth reflection mirror is
aligned with the third reflection mirror and is mounted on the
A-pillar. The second convex lens is mounted away from the A-pillar
and is opposite to the fourth reflection mirror, the second concave
lens is set between the fourth reflection mirror and the second
convex lens and is aligned with the fourth reflection mirror and
the second convex lens. A light beam which would be blocked by the
A-pillar of the vehicle is focused by the first convex lens and
transmitted to the first concave lens, then transmitted by the
first concave to the first reflection mirror, and reflected to the
second reflection mirror. The light beam passes through the front
windshield of the vehicle to reach the third reflection mirror. The
light beam is transmitted to the second convex lens by the second
concave lens after being reflected by the third and fourth
reflection mirrors. The second convex lens is capable of diffusing
the light beam.
[0009] Since the external light beam does not change direction in
passing through the blind region mirror structure, the driver can
see all surrounding scene without distortion, thus promoting safer
driving.

the vehicle body 10. The first lens module 71 focuses any light
beam (not shown) that would otherwise be blocked by the A-pillar 11
of the vehicle body 10, such light beams pass through the front
windshield 30 of the vehicle body 10 to reach the second lens
module 73. The second lens module 73 diffuses the light beams to
eliminate the blind region that is covered by the A-pillar 11.
[0013] FIG. 2 also illustrates the blind region mirror structure 70
shown in FIG. 1. The first lens module 71 includes a first convex
lens 712, a first concave lens 713, a first reflection mirror 715,
and a second reflection mirror 717. The first convex lens 712 is
mounted away from the A-pillar 11 and is roughly parallel with the
A-pillar 11. The first reflection mirror 715 is opposite the first
convex lens 712 and near the A-pillar 11. The first concave lens
713 is located between the first convex lens 712 and the first
reflection mirror 715 and is parallel to and coaxial with the first
convex lens 712. The second reflection mirror 717 is close to the
A-pillar 11, is mounted on the front windshield 30 and is in
parallel alignment with the first reflection mirror 715. The first
convex lens 712 focuses light beams and transmits them to the first
concave lens 713, then the first concave lens 713 transmits the
light beams to the first reflection mirror 715 and the first
reflection mirror 715 reflects the light beams to the second
reflection mirror 717. Finally, the second reflection mirror 717
transmits the light beams to the front windshield 30.
[0014] The second lens module 73 includes a third reflection mirror
731, a fourth reflection mirror 732, a second concave lens 735. and
a second convex lens 737. The third reflection mirror 731 close to

module 71 is opposite to the A-pillar 11 symmetry set. The light
beams reflected by the second reflection mirror 717 pass through
the front windshield 30 of the vehicle body 10 to reach the third
reflection mirror 731. The third reflection mirror 731 reflects the
light beams to the fourth reflection mirror 732, then the fourth
reflection mirror 732 reflects the light beams to the second
concave lens 735. The second concave lens 735 transmits the light
beams to the second convex lens 737 and the second convex lens 737
finally diffuses the light beams. Thereby, the driver of the
vehicle 100 can watch that part of the surrounding scene which is
shielded by the A-pillar 11 of the vehicle body 10.
[0016] The quantity of blind region mirror structures 70 is not
